He was nervous. Which didn't happen often to him. But why wouldn't he be? After all, the Master-while he'd been a friend a very long time ago-had been an enemy. The last time he'd seen him, he had been trying to steal the Doctor's regenerations. Again. But of course, it hadn't worked.
Then the Time War had happened and, despite himself, the Doctor had been forced to put it all aside.
Now? He was actually rather pleased that the Master was alive. And Romana. Because it meant that he truly wasn't alone. Something he hadn't actually started getting used to-and had figured he never would. No, the Doctor had feared the loneliness would consume him-til he met Rose, anyway. She'd kept it at bay, but there were still times when he really just missed someone with the same type of intelligence as himself-and someone who remembered. He knew he was too sentimental for his own good, but he went to the meeting anyway.
Even though it practically had it's own bright, neon sign that screamed 'TRAP'.
The Doctor was already in the diner, of course, and was eating an ice cream. Strawberry, in fact, on a cone. Ice cream was one of the few things that humans got right, in his opinion. When the Master stepped in, he glanced over to him and raised an absent hand in greeting, though an embarrassingly soft part of him wanted to hug him.
